My initial thought about asking for fruit, was maybe she hadn't eaten that morning and her sugar levels were low, rather than water. That can be disorientating if neglected, especially on a rigorous hike.Does anyone have a theory about the asking for fruit? IMO it still smacks of making her presence memorable to the skier (not sure for what reason exactly). If it was on the basis she had found out there was no running water- why not ask for water? If it was because she had run out of fresh food, does that not seem odd when we know this was day one of a three day hike. I know someone was hunting to find out for definite if she actually asked for fruit, or if it was just a badly reported story that has grown legs. Do we have an answer on that yet?
In the light of all that's been ruled unlikely she could have felt uneasy about someone but then shrugged it off. Like someone in the dead of night knocking on someones door if worried about being followed. That seems unlikely too from reading comments here about abduction being unlikely in that environment.
DC seems to be ruling out everything other than abduction or self harm.
